SHOCK-ABSORBER.

Application led December 24, 1917.

To all 'whom t may concern:

Be it known that l, GEORGE H. HAYES, a citizen of the United States, residing at Hazelton, in the county of Barber and State of Kansas, have invented a certain new and useful Improvement in Shoek-Absorbers, of which the following is a specification.

My invention relates to improvements in shock absorbers, adapted for use on automobiles, and particularly adapted for use on the well known Ford cars.

The object of my invention is to provide a novel shock absorber which will to a great extent eliminate bouncing and jolting due to lateral movement of the car body.

A further object of Vmy invention is to provide a shock absorber, which is strong and durable, Vnot liable to get out of order,

simple in construction and cheap to manufacture and which may readily be applied to automobiles now in use.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings', whichi' illustrate the preferred embodiment of my invention, as applied to a Ford car,

Figure 1 is a front elevation of a part of an automobile which is equipped with my improvement.

Fig. 2 is a top view of some of the parts shown in Fig. 1.

Fig. 3 is an enlarged vertical sectional view on the line 3 -3 of Fig. 1.

Fig. 4 is 'an elevation of one of-my improved shock absorbers, shown applied to the rear Vaxle casing and the rear spring,

portions ofwhich are shown.

Fig. 5 is an enlarged perspective view4 of the Vlever which supports vone end of one of the leaf springs of the automobile.

Fig. v6 is a perspective view of the supporting member which is carried by the front axle and to which the lever shown in Fig. 5 is pivoted.

Fig. 7 is an enlarged'perspective viewk of one of the S-shaped springs which'connect the levers and the adjacent leaf springs.

of one of the lever supporting members carried by the rear axle casing.

Similar reference characters designate similar parts in the different views.

1 and 2 designate respectively the front axle and the front leaf spring which carries the load and which is of the usual type. v

8 designates the rear automobile spring, 1shown in F ig. 4, which is of the usual leaf 4 designates the rear axle casing, also shown in Fig. 4, which is of the ordinary construction. i

Four shock absorbers are employed on each automobile, two being applied to theY front load carrying spring 2, and two, similar to the one shown in Fig. 4, being employed to support respectively the two ends Y of the rear load carrying spring 3.

I The two .front shock absorbers are alike in construction, so that a will suffice for both. l Mounted on the front axle 1 is a supporty comprising a supporting member, shown in description of one mounted in a verticalv hole in the axle 1 to which it is secured by means of a nut 6 wlich bears against the under side of the ax e.

An upwardly and inwardly inclined lever 7, F igl 5, is provided with two horizontal outwardly extending arms 8 which embrace opposite'sides respectively of the supporting member 5 to which the arms are means of a horizontal bolt 9.

A horizontal transverse bolt 10, Fig. 5, extends through the upperend of the lever 7, and has respectively pivoted to its projecting ends the upper ends of two S-shaped springs 11, the lower ends of which are respectively pivoted to two transverse pins 12,

pivoted by `f which extend laterally in opposite directions ,from the two vertical arms of a U-shaped clamping memberl, Figs. 8 and 9, which embraces the spring 2 to which it is secured by two bolts 14 which extend through theaims' of the member 13 and bear the under side of the spring 2.

For pivotally supporting the adjacent end of the spring 2, upon the lever 7, there are provided two links 15, the lower ends of( which are pivoted to the 'adjacent end of the spring 2 by a bolt 16, Figs. 1 and 10.

The upper ends of the links 15 are pivoted to a transverse bolt 17, which extends against iwardly extending arcuate portion 18, the.

Vio

through the lever 7 transversely to the axle 1. v Y

yFor limiting the upward movement of the lever f? and serving as a stop therefor, the

supporting'member is provided with, an ininner end of which is vadapted to be struck bythe 'lever 7, as is best shown inFig. 10.

It will be noted that thek clamping plates 13are secured tothe spring 2 intermediate oftheends thereof andthe, central portion of the spring whichcarries the load.

Y lt will also be noted that the links 15 are pivoted to the lever lwinte'rmediateof the fulcrum bolt 9 and the bolt 10, to which the v upperend of the spring 11 isattached.

By means vofxthi's construction, when the load forces the spring 2 downwardly, the levers ,7 will b-eswung' downwardly bythe .supporting links 15, thereby further com- The outer ends ofthe spring 2 and the levers Y 7 willthus be stopped in. their upward moveV ment, and the springs 11 will be compressed by and -will resist'yieldingly the further up wardmovement ofthe middle portion of the spring2. y

The springs 1 1 thus, to a great extent, eliminate upward and downward jolting. The springs 1 1 further to a great extent eliminate shock due to lateral movement of the loadVV Asthe load with the spring 2 moves. laterally in either direction, being supported bythe links 1,5,v which are suspended fromthe levers i7, so as to, permit endwise movement of the spring 2, such lateral movement of the spring 2 will vbe resisted'by the springs 11, one of'which will befurther compressed and theY other of which will expand."

llt will be noted that the S-shaped springs 11 are disposed in different vertical planes Y from the vertical plane of the leaf spring 2. By means of this construction, thereis noj liability of the springs 11 being crushed be tween the spring 2 and the ylever 7'. Furthermore, the vfull elasticity of the springs is afforded; The ,S-shapedspring provides onewhich is `very strong and instantaneous 1n action. L Y' Y stop Each of the shock absorbers which Support the rea-r spring 3,7is constructedlike each of those employed to support the front spring2, and already described, ezfzceptingY Y that there is substituted for the supporting Vmember 5 asupporting memberl 19,V which extends 4through and is secured to .the adjaiug. 4.

rlhe, supporting Vmember 19 y is pro-vided` `with an arcuate portion k21,-simil'arto Ythe arcuate portionV 18-V and which servesfas'a for the lever in the upward movementV of thelatter. The lever 7 is supported pivotally by a transverse "bolt 9, corresponding in function and location to the bolt 9 already described; The l S-shaped springs '11 are .65 I ycent end of the axle casing 4C byra nut'20,"V Y

.75 supported by the clamping-plates 18 mov`unt-l y edron the spring 8 in the' same manner as the corresponding yclamping plates are,`

mounted on the frontspring'2. The operation of the rear shock absorbers is the same asV the; operation oftheV 'front Vshock absorb-V erS-which-has already been described. I

I do not limit myinvention to-the'structure shown and described, as modifications,

within the scope of the appendedclafims,

may be made without departingl from .the-

spirit of vmy invention.
